Written Information Security Plan
6.2 Multi-factor authentication (MFA)
Requirement: 16 CFR 314.4(c)(5)
MFA is required for any individual accessing any information system that holds or connects to customer information, not only remote access. This includes tax software, email, the client portal, cloud storage, remote access tools, the password manager and administrative accounts.
Any exception requires the QI's written approval of a reasonably equivalent or more secure control, recorded in Appendix E.
What's different here: The IRS sample plan covers MFA for remote login only. The Safeguards Rule covers any information system, so this section is intentionally broader.
Drafting notes like this appear in the kit and are removed when you finalize your plan.
